In this episode of Chopper's Brexit Podcast, former Tory leader Iain Duncan Smith warns Theresa May should not quit as Prime Minister over the stalled Brexit talks and instead “stick it out". Meanwhile, The Telegraph's Europe Editor Peter Foster looks at the latest developments in negotiations in Brussels. Chopper also speaks to former Environment secretary Owen Paterson, who says Mrs May should threaten to walk away from talks and start negotiations to trade on World Trade Organisation rules after Britain leaves the EU. And we hear from shadow Northern Ireland secretary Vernon Coaker, who believes: “That walk away approach can only lead to potential disaster for us all.”
